[1941 Tming Adjustments and More]

Hello,  I just wanted to say thank you to all,   by reading most of your  post and comments  I don't have to ask many questions. As my boss just perched a 1941 Buick Special  with dual carbs. 

Before  and after I tuned it up it has a bad ( I don't know how to explain it )   but it's like it has an on and off switch at half throttle  but if you go to wide open throttle it don't miss a beat. Now if you go to wide open from an idle it's has no problem. Does anybody have any info for me ?   Thanks Vic

[1933 Buick series 90]

Hi Everybody,  I'm working on 1933 Buick series 90. I was reading post from other questions on this site. They were talking about the oil filter  (or lack of) on a 1936 the the same apply to the 1933.

Shouls I feave the thing alone and just change the oil.  It calls for 20w nondetergent  and I was given 30w. non d.  I know weight is baced on temperature  so the 30 w should be ok am I right?
